Datasheet for the MAX6675, the Maxim cold-junction-compensated K-type thermocouple-to-digital converter with a read-only SPI-compatible serial output. The PDF is compact at 130 KB and covers pinout, electrical characteristics, timing diagrams and the conversion data format. Technicians use it when diagnosing temperature readouts on soldering stations, reflow ovens and hobby controllers, checking supply voltage, thermocouple connections and the serial clock and chip-select lines. Verify the part marking on the chip matches before relying on the figures.
